SPRINKLING GRANULAR SUBSTANCES ON DOUGH IN BISCUIT-CUTTING MACHINES.

Specification of Letters Patent.

Patented Feb. 27, 1906.

To (1 whom it may concern:

Be it known that we, THoMAsVmARs and JOHN VIGARS, the Younger, subjectsof the Kingof Great'Britain,res1ding at Earlestown, in the county ofLancaster, England, have invented new'and useful Improvements insprinkling Granular Substances on Dough in Biscuit-Cutting Machines,of'which the ,following is a specification.

The object of the invention is to provide appliances whereby thesprinkling or distributing of sugar, currants, or other powder orgranular substances onto sheets of doug to form biscuits or ontodoughcut out in" the form of biscuits may be automatically, moreefiiciently, and uniforml accomplishedthan has been practicable hiterto. 'j

Our invention will be clearly understood from the accompanying drawin s,on which- Fi re 1 is an end view, and F gitu inal section, of appliancesunder. the in;

vention as applied to a biscuit'-eur ,ting niav chine, part the frameand canyng-iband of which is shown, the otherv parts, belnglinnecessaryfor the pur ose of this, speelfica tion. Fig. 3 is a detail view. Figs.A and are modifications. Fig. 6 is a sectional view showing theattachment of the-slides 1'6 and plate 18 to the cheeks I9. I

-1 is a hop er for containing the substance to be sprinli above thesheet of dough 2 and referably rests on a bar or plate 3, which has figs4 free to slide up or down in uides 5, supported by the main frame 6 oft e biscuit-cutting machine. I r resents 'screws engaging with the lugs4,'so t at the bar 3, with the hop er andconnections, can be raised orlowere 8 is the dough-carrying band.

9 is an endless travelin belt or sheet or the like, the upwardly-asceziing part of which is within the hopper 1, and resting on the backthereof, while the descending part is outside The arrows show thedirection of motion.

10 11 are top and bottomrollers, round which the sheet 9 passes. Theshafts 12 13 .of the rollers are carried in bearings 14 15,

that, 14, of the top roller being movable in slides 16 and adjustablebyscrews 17 for regulating the tension of the sheet 9. A nonrotatinadjustable bar might be used instead o theroller 11. The slide 16'andthe cesses '23-, into which? small ig, 2 is a lon-" led. Thehopper isdisposed back late 18 of the hopper are attached to side p ates orchecks 19, pivoted on the shaft 13, so that the slope of the sheet canbe varied.

20 represents set-bolts for-fixing the slides 16 in the desiredposition.

21 is a trough partly inclosing the bottom roller 11 and sheet 9, so asto prevent leakage or spilling of the material or substance at thebottom of the hoppe'n. l 1 v 22 is ratchet-and-pawl gear for rotatingthe roller- 11, "and thus causing the 'sheet' 9 to travel- The surface;of the belt or sheet 9 .next to the substance in -the-hopper' is formedunockets, grooves, or reuantities of the substance enteria'nd as the seet travels u ward in the hopper are carried up over t e top roller,whence'asthe sheet turns downevenly with small Ward the substance fallsout of the pockets lento the sheet of dough 2, spreadin out as 1t fallsand being. distributed uniform y on the dough as-such dough travelsalong. By

varying the slope of the sheet as before mentioned the capacity of thepockets or grooves 23 is varied, so that more or less substance is takenup. V

The bottom of the pockets or grooves may be. movable, for instance, inthe form of screws 24, as shown on enlarged scale in Fig. 3, so that byscrewing these' 1n or out the capacity of the ockets can be increased'ordiminished, as esired,'-f or any class of work.

Instead of ressions the s eet 9 may, as shown in Fig. 4, e provided withprojecting ins 25 or rojecting -transverse strips or ars 26. he pins orstrips will carry upon their upper suraces a certain quantityofsubstanceand I allow it to fallon their downward travel, as

described for the ockets. The pins may be screwed more or ess into thesheet to vary the amount of substance carried. If the dough travelsintermittently, the sheet 9 'should also be operated intermittently; but

if the dough travels continuously then the sheet 9 should also travelcontinuously, spur t .or like gearing being used instead of th ockets,grooves, or like deratchet-and-pa'wl gearing 22; 'To assist'in spreadingthe substanceasit falls from the pockets, -a' deflecting-plate 27 may beused. guiding-stripsaf- 28 represents pro'ecti'n fixed to the inner si eof t belt or sheet 6 at each side, and 29 represents circumferentialgrooves in the top and bottom rollers 10 1 1, in which the strips 28run, thus preventing the sheet 9 from moving sidewise and keeping it Itight across its width and in true working position. To confine thefalling substance to particular parts of the dough, we may arrange inthe line of fall a plate 30, having openin s 31 of any desired shape orsize, through whic the substance falls and coats the doughin corresponding shapes. The plate 30 is supported in any convenient Way, say byarms 32, from the bar 3, or the late 30 may be arranged to rest directlyon t 1e main frame 4. To allow of removing any of the substance that maycollect on the non-perforated parts of the plate 30, such plate may belifted off the arms 32 from time to time and another one substituted ora solid plate 33, movable in guides 34, may be slid under the plate 30and closing the opening 31, and then all the accumulated substance maybe brushed cff the plate 30'without falling through the openlugs 31.

Fig. 5 is a sectional view of a modification under our invention. Inthis case instead of an endless traveling belt or sheet a large roller35 is used, which forms the back of the hopper. The surface of theroller is formed with ockets 23 or pins 25 or strips 26, as beforeescribed, which carry the material from the hopper up over the top ofthe roller and then drop it on the dough.

What we claim, and desire to secure by Letters Patent, is g 1. Incombination with biscuit-machines a hopper for containing the substanceto" be dis-' tributed, a conveyer having an uneven sur face adalpted tosupport a granular substance, the upward moving part of the conveyerpassing \through the hopper while the downward-moving part passesoutside the hopper, and mechanism for moving the conveyer to dropthegranular substance on dough underneath the conveyer, substantially asdescribed.

2. In combination with biscuit-machines a hopper for containing thegranular substance to be distributed, an endless traveling sheet havingan uneven surface passing round rollers at the top and bottom of thehopper the upward moving part of the sheet passing through the hopperwhile the downwardmoving part passes outsideethe hopper, and mechanismfor moving the sheet to drop the granular substance on dough "hnderneaththe sheet, substantially as described: 3. In combination withbiscuit-machines a hopper for containing thegranular substance to bedistributed, an endless traveling sheet having an uneven surface passinground rollers at the top and bottom of the hopper the upwardmovingpart-of the sheet passing through the hopper while the downwardmovingpart paseesoutside the hopper, the upper roller beiiig-adjustablysupported on movable side plates and the back plate of the hopper beingalso fixed to the 'side plates,

and mechanism for moving the sheet to drop the granular substance ondough underneath the sheet, substantiallyas-described.

4. In combination with biscuit-machines a hopper for containing thegranular substance to be distributed, an endless traveling sheet havingan uneven surface passing round rollers at the top and-bottom of thehopper the upward -moving part of the sheet passing through the hopperwhile the downwardmoving part passes outside the hopper, circumferentialgrooves in the rollers and guiding-strips on the inner side of thetraveling slieet fitting in thegrooves, and mechanism for moving thesheet to drop the granular substance on dough underneath the sheet,substantially as described.

5. In combination with biscuit-machines a hopper for containing thesubstance to be distributed, a conveyer having an uneven surface adaptedto support a granular substance the upward-moving part of the conveyerpassing through the hopper while the downward-- moving part passesoutside the hopper, devices for varying the supporting capacity of theuneven conveyer-surface, and mechanism for moving the conveyer to dropthe granular substance on dough underneath the conveyer,substantially'as described.

6. In combination with biscuit-machines a ho per for containing thesubstance to be distri uted, a conveyer having an uneven sur faceadapted to support a granular substance the upward-moving part of theconveyer passing through the hopper while the'downwardmoving-part passesoutside the hopper, a perforated plate below the conveyer, a solid platearranged to be slid under the perforated plate, and mechanism for movingthe conveyer to drop the granular substance through the perforated plateonto dough underneath such plate, substantially as described.
